Yersinia pestisis a gram negative, bacillus shaped bacteria that prefers to reside in an environment lacking oxygen (anaerobic). It is typically an organism that uses the process of fermentation to break down complex organic molecules to metabolize.

Can the bubonic plague spread through air?

Pneumonic plague affects the lungs and is transmitted when a person breathes in Y. pestis particles in the air. Bubonic plague is transmitted through the bite of an infected flea or exposure to infected material through a break in the skin.

How did the bubonic plague spread?

The Black Death is believed to have been the result of plague, an infectious fever caused by the bacterium Yersinia pestis. The disease was likely transmitted from rodents to humans by the bite of infected fleas.

Can bubonic plague spread from human to human?

Can you be immune to the plague?

Scientists examining the remains of 36 bubonic plague victims from a 16th century mass grave in Germany have found the first evidence that evolutionary adaptive processes, driven by the disease, may have conferred immunity on later generations of people from the region.

Can you get the plague twice?

It is possible to get plague more than once. How do you get plague? It's usually spread to man by a bite from an infected flea, but can also be spread during handling of infected animals and by airborne droplets from humans or animals with plague pneumonia (also called pneumonic plague).

Given that the virus has spread almost everywhere in the world, though, such measures alone can't bring the pandemic to an end.
